Embodiment 1

[0058] The embodiment of the present invention provides a method for switching data services in a space-heterogeneous integrated network, such as figure 1 shown, including:

[0059] Step S102, receiving a link switching request from a first user, wherein the first user is a user moving from the coverage area of ​​the first satellite network to the coverage area of ​​the second satellite network.

[0060] Specifically, the user in this embodiment of the present invention refers to a user terminal device.

[0061] Step S104, based on the link switching request, perform a data tunnel change operation on the initial link, so as to add an updated link between the first user and the second user, wherein the second user is a user that conducts data services with the first user For users, the initial link is the link when the first user implements data services based on the first satellite network and the second user.

[0062] Step S106, switching the data service from the initial l...

Embodiment 2

[0155] An embodiment of the present invention provides a device for switching data services in a spatially heterogeneous integrated network, such as Figure 11 shown, including:

[0156] The receiving module 100 is configured to receive a link switching request from a first user, where the first user is a user moving from the coverage area of ​​the first satellite network to the coverage area of ​​the second satellite network;

[0157] The link modification module 200 is configured to perform a data tunnel modification operation on the initial link based on the link switching request, so as to add an updated link between the first user and the second user, wherein the second user is and the first user For users who perform data services, the initial link is the link when the first user implements data services based on the first satellite network and the second user;

[0158] The switching module 300 is configured to switch the data service from the initial link to the update...

Embodiment 3

[0185] An embodiment of the present invention provides a computer-readable medium with a non-volatile program code executable by a processor, including: the program code enables the processor to execute the data service in the spatially heterogeneous integrated network described in Embodiment 1 Switch method.

[0186] In the embodiment of the present invention, the program code causes the processor to execute the data service switching method in the space heterogeneous integrated network described in the first embodiment, and an update link is added between the first user and the second user, and through the update The link enables the first user to realize data service with the second user through the second satellite network; then switch the data service from the initial link to the update link at the target time, the target time being that the first user is in the first satellite network and the second At the time of the overlapping coverage area of ​​the satellite network,...

Abstract

The invention provides a data service switching method, device and system in a space heterogeneous integrated network, and relates to the technical field of network system switching in space communication. The method comprises the following steps: receiving a link switching request of a first user; changing a data tunnel of the initial ink based on the link switching request in order to provide anupdate link between the first user and a second user, wherein the second user is a user performing a data service with the first user, and the initial link is a link for realizing a data service forthe first user based on a first satellite network and the second user; and switching the data service from the initial link to the update link at a target moment, wherein the target moment is a momentat which the first user is in an overlapped area of the first satellite network and a second satellite network. Through adoption of the data service switching method and device, the technical problemof incapability of realizing senseless switching of the data service among heterogeneous networks is solved in an original space heterogeneous integrated network.

Description

technical field [0001] The invention relates to the technical field of space communication, in particular to a data service switching method and device in a space heterogeneous integrated network. Background technique [0002] With the rapid development of mobile communications, mobile communications have put forward higher requirements for the capabilities of space information networks, requiring space information networks to ensure communication "global coverage, interconnection, rapid response, and integrated applications." Based on the current diversity of spatial information networks, in order to meet the above requirements, the comprehensive application of spatial heterogeneous integrated networks needs to be studied in depth. [0003] Considering the dynamic nature of users in the mobile communication process, when users change from one cell to another, the communication network that provides users with data services has changed. In order to ensure uninterrupted data ...
